Competitive eSports. Drug Testing?

Competitive eSports. Drug Testing?

I'm just curious if Riot has an official policy on performance enhancing drugs. Now that they are trying to promote a weekly competitive scene, are they testing to make sure players aren't using speed to gain a competitive edge?

Edit: I said performance enhancing drugs. Such as Adderall.
Edit 2: Scroll down in this article to where it says "Getting a perscription for adderall is not hard." http://www.theverge.com/2012/7/26/31...autionary-tale It explains the effects of Adderall pretty well for those of you who don't believe it could benefit a competitive gamer.
